- the invention relates to a control device 1 for opening / closing a valve 16 of a container 1 1 valve and an assembly comprising the container 1 1 valve and the device 1 control.
- This opening / closing control device 1 is more particularly intended to allow the opening / closing of the valve of the type shown in FIG. 5.
- This valve 16 comprises a valve body 17 provided with a shutter 19 of the orifice 18 made at least partially of a magnetic material and mounted movably inside the valve body 17 between an open position of the orifice 18 and a closed position of the orifice 18, and a member 20 for returning the shutter 19 of the valve 16 in the closed position of said orifice 18.
- the body 17 of the valve 16 has the shape of a thimble provided at its end with an opening forming the orifice 18 of the valve 16, and the shutter 19 is slidably mounted at the interior of the valve body 17.
- This finger communicates, by its base, with the container which it equips.
- the return member 20 is itself a helical spring which extends between the shutter and the valve body.
- the detail of the interior of such a valve 16 will not be provided because it is well known to those skilled in the art.
- the orifice 18 of the valve 16 is conventionally used to allow, in the open position, emptying the container it equips.
- this valve 16 is fixed to a closure cap 14 of a container January 1, the details of which will be provided below.
- the device 1 for opening / closing the valve 16 of the container 1 1 comprises at least one location 3 for receiving the valve 16 of the container and, associated with each location 3 for receiving the valve 16, a control system 5 when the valve 16 is opened. For the sake of simplicity of the figures, there has been shown in each case a single location 3 and therefore a single associated control system.
- the receiving location 3 of the valve comprises a housing 31 inside which the valve 16 of the container 1 1 is adapted to be inserted axially at least partially.
- This housing 31 which generally has the shape of an elongate cavity, can be blind or through, depending on the embodiment of the control device 1. It may be delimited by a continuous or discontinuous circumferential wall, to form an equally lateral opening.
- the device 1 further comprises a control system 5 opening the valve 16 positionable at least partially around said location s.
- This control system is, in the state positioned around the location 3, configured to maintain the shutter 19 of the valve 16 in the open position of the orifice 18 of the valve 16, in the positioned state of the valve 16 in said location 3.
- This control system comprises at least one permanent magnet 6 able to exert a force of attraction and repulsion on the shutter 19, in the direction of an opening of the shutter 19.
- the system 5 control comprises two permanent magnets positioned opposite one another and separated from each other by the housing 31 defined by the valve receiving location 3. These permanent magnets are neodymium type magnets.
- the two magnets 6 are therefore positioned on either side of the valve 16 in the positioned state of the valve 16 in the location 3, so that the force exerted by these magnets is sufficient to attract the shutter 19 , made for example of magnetic material, towards the end of the valve opposite to that provided with the orifice 18 of the valve 16 and called the cylinder head.
- the valve is then open.
- the attraction or repulsion force exerted by the magnets on the shutter in the direction of an opening of the orifice 18 of the valve is greater than the force exerted by the return member on the valve.
- shutter 19 When the valve is removed from between the magnets, the return member closes the valve.
- FIG. 2B differs from FIG. 2A only in that a spring 4 equips an open end of the housing 31, which is in the form of an elongate cavity, this spring tending to return the valve to the outward position of the housing corresponding to the closed position of the orifice of the valve.
- This spring 4 is therefore able to be compressed in the introduced state of the valve 16 in the housing 31, since it is interposed between the cap of the container and the open end of the housing of the control device.
- the magnets 6 disposed around the receiving location 3 of the valve can be made fixed with respect to said location, as shown in Figures 1 and 2A, 2B.
- These magnets 6 can also be made mobile along said location 3.
- rails defining a guide path of the magnets 6 may be provided along the location 3 for a manual drive moving the magnets along said location.
- the control device 1 may comprise means for driving the permanent magnets 6 along said location 3.
- These means 25 for displacing the control system 5 comprise, for example, a pneumatic actuator 26, such as than a cylinder.
- An example of an actuator is shown in FIG. 10.
- This actuator 26 comprises an annular chamber 261 and a sleeve 262 that is coaxial with the chamber. This sleeve is adapted, over at least part of its length, to surround the receiving location 3 of the valve. This sleeve 262 is slidably coupled to the chamber 261.
- the chamber 261 is a chamber able to be pressurized and connected by a pneumatic circuit 263 closable to a source of gas under pressure.
- the closure member 264 may be a solenoid-type member.
- the sleeve and the chamber respectively form the equivalent of the rod and the body of a pneumatic cylinder.
- the sleeve carries the magnets 6 of the control system.
- a spring 265 may be provided to bias the sleeve 262 towards the chamber 261.
- the container 1 1 that equips such a base can affect a large number of forms.
- this container comprises a flexible pouch 12 deformable under the action of a pressure exerted on the outer surface of the bag 12 to allow, in the compressed state of the bag 12 and open of the orifice 18 of the valve 16, an emptying of the pocket 12.
- the container 1 1 further comprises an overpack 15 of the bag 12.
- This overpack 15 which constitutes a rigid or semi-rigid shell for protecting the bag 12, is here in the form of an elongated body equipped with a neck, which gives it the appearance of a bottle.
- the pocket 12 is housed inside the overpack 15 and is at least partially plated against the inner wall of the overpack 15.
- This pocket 12 has an opening flanked by a flange, which is pressed against the outer peripheral edge of the neck of the bottle constituting the Overpack 15. Because the body of the bag 12 has a circumference greater than that of the overpack neck, the exit from the overpack pocket is not possible. It is also possible to locally weld the bag 12 to the overwrap 15. Thus, the bag 12 is kept inside the overwrap 15.
- the bag 12 therefore has an opening which constitutes the liquid filling opening 13 of the bag 12.
- This filling orifice 13 is closed by means of a stopper 14 which is screwed onto the overpack neck 15.
- a port 13 for filling the bag could have been provided at another location, without departing from the scope of the invention.
- the emptying of the bag 12 is effected by compression of the bag 12 under the action of a pressure exerted on the outer surface of the bag 12.
- This pressure can be exerted in different ways.
- the outer surface of the pocket 12 delimits, with the inner surface of the overpack, a closed space 23 in communication with the outside through an orifice formed in the overwrap, and shown at 22 in the figures.
- This orifice 22 may be connected, during the emptying phase of the bag, to a source of gas under pressure to allow pressurization of this closed volume.
- the opening / closing control device 1 then comprises a frame 2 equipped with a pressurized gas supply circuit 7 connectable to a source 21 of gas under pressure.
- the location 3 for receiving the valve 16 of the device and the control system 5 for opening the valve 16 are formed at least partially on the frame 2 and the circuit 7 for supplying pressurized gas to a source 21 of pressurized gas is configured to generate a pressure on the outer surface of the bag 12 of the container 1 1, in the positioned state of the valve 16 of the container 1 1 in the location 3 of receiving the valve 16 of the device 1.
- the supply circuit 7 has a duct section disposed on the frame 2 near the valve receiving location 3 of the frame 2.
- This duct section of the supply circuit 7 is inserted in the orifice 22 formed in the overwrap 15 of the bag 12 in the positioned state of the valve 16 of the container 1 1 in the location 3 of receiving the valve 16 of the device 1 to supply gas under pressure the space 23 closed delimited between the outer surface of the pocket 12 and the inner surface of the overpack.
- this circuit 7 for supplying pressurized gas could have been envisaged depending on the design of the container and the position of the location of the compression zone of the bag on said container. .
- the pocket 12 therefore tends, during its emptying, to retract inside the overpack. Once completely retracted inside the overpack 15, it is necessary, to refill the pocket, to redeploy and reposition at least partially supported within the overpack. To do this, it is necessary to open the orifice 18 of the valve 16 and to inflate the bag 12 by blowing the air inside the bag 12, via the orifice 18 of the valve 16 in position opened.
- the orifice 18 of the valve 16 is thus no longer used as a liquid draining orifice of the bag, but as a gas filling orifice of the bag 12. To allow this filling, it is necessary that the orifice 22 of the overpack is exhausted, if it was previously connected to a source of pressurized fluid.
- an opening / closing control device 1 in the form of a liquid recharging aid installation of the bag according to FIGS. 6 to 8 may be used.
- This installation comprises a frame 2 equipped with a closable circuit 8 for supplying pressurized gas connected to a source 21 of pressurized gas, the location 3 for receiving the valve 16 and the control system 5 for opening the door.
- valve 16 of the device 1 being formed at least partially on said frame 2.
- the closed circuit 8 for supplying pressurized gas connected to a source 21 of pressurized gas comprises a connector 9 positioned at least partially around the location 3 of receiving the valve 16 in a position in which it covers an area of the receiving location 3 adapted to be occupied at least partially by the orifice 18 of the valve 16 in the disposed state of the valve 16 inside of said location s to allow the positioned state of the valve 16 in said location s and in the open position of the orifice 18 of the valve 16 a gas supply of the pocket 12 of the container 1 1 in the direction of a inflating the pocket 12.
- This connector 9 forms at least the portion of the gas flow pipe which terminates at one end by a pivoting tip which caps the valve portion which projects from the housing 31 through.
- This gas flow line is adapted to be connected at its other end to a source of gas under pressure, in particular to a compressor or other compressed air generator.
- the nozzle of the pipe thus forms the part of the coupling 9 mounted pivotably on the frame 2 for the displacement of the connector 9 between a position remote from the receiving position 3 of the valve 16 and the close position of receiving location of the valve 16 in which it is disposed at least partially around the receiving position 3 of the valve and covers the area of the receiving position 3 of the valve of the container 1 1 able to be occupied by the orifice 18 of the valve in the state disposed of the valve 16 within said location 3.
- This pivoting portion of the coupling closes the end of the housing 31 through.
- the gas circulation pipe equipped with the connector 9 is a connection closable by a closure member movably mounted between a closed position and an open position.
- This shutter member may be a pneumatic contactor integral displacement of the movable part of the connector.
- This shutter member is configured to move from the closed position of the connector 9 to the open position of the connector 9 during the displacement of the connector 9 in the direction of approaching the receiving location 3 of the valve 16.
- 9 shutter can thus include a spring-loaded ball which, in the close position of the connection of the location 3 of receiving the valve, is in the open position of the gas flow conduit formed.
- the container is then placed in the installation with the valve positioned between the magnets.
- the orifice 18 of the valve 16 is then in the open position, the shutter 19 of the orifice 18 being displaced in the open position of the orifice 18 against the return member 20 under the action of a magnetic force of attraction or repulsion exerted by the magnets on said shutter 19.
- the pivoting portion or tip of the connector 9 is pivoted to overlie the end of the valve provided with the orifice 18 of the valve, without generating direct contact between the orifice 18 of the valve and the connector 9.
- the connector may be internally provided with an annular seal to isolate the orifice 18 of the valve from the outside and improve the effectiveness of the inflation.
- the closure member of the connector is then in the open position. Air at low pressure, between 0.1 and 0.5 bar, is sent into the bag via said orifice 18 of the valve 16, in order to put the bag back into the overpack.
- the inflation of the pocket usually takes ten to twenty seconds.
- the operator detects, at its product, that the bag is in place, that is to say generally at least partially pressed against the overpack.
- a new container can be installed in the installation, for a new pocket inflation operation.
- the device 1 is in the form of a fluid dispensing gun 10 and comprises a hollow base body 100 equipped with a handle 101, a trigger 102 coupled to said base body 100 and movably mounted relative to said base body 100, and at least one passage 103 of fluid arranged in the base body 100 and / or the handle 101.
- the receiving location 3 of the valve 16 of the device 1 is formed at least by the or cavity of the hollow base body 100 of the fluid dispensing gun 10 and the opening control system of the valve of the device 1 is worn. by the trigger 102.
- the location 3 for receiving the valve is extended in the direction of the trigger.
- An opening control device as described above can therefore be realized in a large number of forms.
